HOMER L. HAWKINS, OF SANTA BARBARA, CALIFORNIA.

BULKHEAD-BOISE.

Specification of Letters Patent.

Patented July 27,1915.

Application filed July 20, 1914. Serial No. 852,112.

To all whom it may concern:

Be it known that I, HOMER L. HAwKiNs, a citizen of the United States,residing at Santa Barbara, in the county of Santa Barbara and State ofCalifornia, have invented certain new and useful Improvements inBulkliead-l-loists; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to hoisting devices and more particularly to adevice of this character especially designed for lifting the bulk headsin railway refrigerator cars.

Another object is the provision of a device of this character of lightand durable construction which may be conveniently moved from place toplace by one man.

Another object is'the provision of a hoisting device embodying a basemember adjustably supporting the frame structure of the hoisting device,whereby the latter may be raised and engaged against the ceiling of thecar or other compartment in which the device is located. 1

With these and other objects in view, the invention consists in thenovel construction, arrangement, and formation of parts as will behereinafter specifically described, claimed and illustrated in theaccompanying drawings. in which:

Figure 1 represents a fragmental sectional view through a refrigeratorcar of ordinary construction, showing the hoisting device operativelypositioned therein; Fig. 2 represents an enlarged side elevation, partlybroken away, of the. hoisting device. F 3 represents a front elevationthereof. Fig. 4 represents an enlarged detail view, partly broken away,of the lower portion of the hoisting device. Fig. 5 represents an enlarged front elevation, partly broken away, of the upper portion of theframe of the hoisting device.

Referring to the drawings in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral6 indicates the web portion of a substantially U-shaped base designatedgenerally by the numeral 7 and includin the upstanding parallel ends 8.The base? is preferably formed of sheet metal of adequate thickness andthe ends 8 thereof adjacent the web portion 6 are apertured to receivebolts 9 slidably received within elongated slots 10 formed in the lowerextremities of the side members 11 of the main frame of the hoistingdevice which is preferably formed of channel iron, as illustrated, andis reinforced at intervals by spaced connecting bolts 12. At the top ofthe side member 11 of the frame an inverted Ushaped member 13 is securedby suitable bolts or other means extended through the free terminalsthereof and braced with the side members 11 by the angular bracing bars14- having apertures in their upper extremities rotatably receiving theshaft 15 on which bushings 16 are arranged between the bracing bars 14-and the side members 11 of the frame. A pulley 17 is rotatably mountedon the shaft 15 between the parallel portions of the bracing bars 14 andis provided with a suitable groove 18 adapted to receive the hoistingcable 19 carrying a hook 20 at one end and permanently secured at itsopposite extremity to a winding drum 21 rotatably mounted between theside members 11 of the frame and carrying a gear wheel 22 at one endexteriorly of the frame structure mounted within a suitable housing 23and meshing with a worm 24 formed with a hand crank 25 whereby the drum21 may be rotated.

The web portion of the top U-shaped mem ber 13 is prefererably arrangedat an oblique angleto the frame structure, as clearly illustrated inFig. 1, and the upper extremities of the bottom U-shaped member or base7 are apertured to receive bolts 23 pivotally supporting the liftingmember 24" which is substantially U-shaped and provided with angularlydirected free ends 25.

The extremities of the angularly directed ends 25 are pivotallyconnected at 26 to the adjacent portion of the side members 11 of theframe, whereby when the web portion of the U-shaped lifting member 24 isdepressed the frame structure is carried upwardly into engagement withthe ceiling 26 of the car, the bolts 9 sliding within the slots 10 inthe lower extremities of the side members 11 of the frame structure.

In use, the base 7 is arranged on the floor 28 of the car in proximityto the bulk head 29, and the frame structure is arranged at the angle,relative to the bulk head 29, illustrated in Fig. 1. The frame structureis sub sequently elevated by depressing the lifting member 24 moving thetop U-shaped member 13 into firm engagement with the roof 27 of the carand thus effectively locking the hoisting device in position foroperation. The hook 20 of the cable 19 is then engaged with the lowerextremity of the door or bulk head 29 and the crank 25 manually orotherwise operated to wind the cable on the drum 21, thus raising thebulk head 29.

While I have here shown the hoisting device in use only in connectionwith the bulk heads of railway refrigerator cars, it will be understoodthat the samemay be employed for various other purposes, as forinstance, forloading the car and numerous other useful purposes.

What I claim is: V

1. A hoisting device comprising'a base, a pair of side members extendingupwardly therefrom, a U-shaped member connecting the upper extremitiesof said side members, bracing bars connecting said side members and webportion of said U-shaped member, a shaft rotatably mounted in the upperextremity of said side members and through said bracing members, a pullyrotatably mounted on said shaft between said bracing members, a windingdrum rotatably mounted in said side members, means for rotating saidwinding drum, and a cable secured at one end to said winding drum andextending over said pulley.

2. A hoisting device comprising a base, a frame structure pivotallysupported in said base including a pair of side members, and meansconnecting said side members at spaced intervals, means for moving saidframe structure upwardly within said base member, a winding drumrotatably mounted in said frame structure, means for manually rotatingsaid winding drum, a pulley rotatably mounted in the upper portion ofsaid frame structure, and a cable secured at one end to said windingdrum and extending upwardly over said pulley.

3. A hoisting device comprising a base member substantially U-shape information and having the free ends directed upwardly, a pair of sidemembers having longitudinal slots in the lower extremities thereof,bolts secured in said U-shaped member and slidably positioned withinsaid slots, a substantially U-shaped member pivotally secured to theupper extremities of said U-shaped member and having angularly directedends pivotally secured to said side members, a winding drum rotatablymounted in said side members, a pulley rotatably mounted in upperportions of said side members, and a cable secured at one end to saidwinding drum and extending upwardly over said pulley.

A. A hoisting device comprising a base member, a frame pivotally mountedin said base member, means for raising said frame structure in saidU-shaped member, a winding drum rotatably mounted in said framestructure, means for manually rotating said winding drum, a pulleyrotatably mounted in the upper portions of said frame structure, .and acable secured at one end to said winding drum and extending upwardlyover said pulley.

In testimony whereof I aflix my signature in presence of two witnesses.
